Is mental illness the biggest problem facing teens?

Seventy percent of American teens see anxiety and depression as “major problems” among their peers, according to a new study from the Pew Research Center.

In fact, teens are far more likely to cite anxiety and depression as big problems among their peers than they are to cite bullying, drug addiction, and alcohol use. (Fifty-five percent of teens see bullying as a major problem; 51 percent see drug addiction as a major problem; and 45 percent see alcohol as a major problem.)

The data is based on interviews with a representative sample of 920 people ages 13 to 17.
